method
Ease.in
Ease.in(t) -> fixed
Returns t * t — motion that starts slow and speeds up. Feed the result to Math.lerp as the blend amount so a value accelerates into its target. The input t is expected in 0.0..1.0.
Example
program Demo {
handler Step phase Update {
let x = Math.lerp(start_x, end_x, Ease.in(progress))
}
}
